FEAR is nothing to be ashamed of. Everybody at times has that sinking feeling in the pit of the stomach. It’s what you do about it that counts. The Army, faced by the job of conditioning millions of men for the change from peaceful pursuits to the terrors of the battlefield, has discovered some interesting facts about fear and the way to control it.

Has Precision Bombing Failed?
Out of the fog of uninformed criticism comes an authoritative appraisal of the part our Liberators and Fortresses are taking in the around-the-dock pounding that is softening up Hitler's European citadel.

WILLIAM S. FRIEDMAN
THE day after a combined task force of Boeing Flying Fortresses and Consolidated Liberators put the German sub base at Vegesack out of action for a season, General Ira Eaker, commander of the Eighth U. S. Air Force, told American and British journalists that the experimental phase of high-altitude bombing had been concluded and that the business of crippling the Axis within its own preserves was beginning as of that day and in full earnest.

Secret Rocket Weapons Blast Tanks and Planes
DID YOU KNOW THAT ROCKETS HAVE COME BACK WITH A BANG IN WARFARE?
Buck Rogers' world comes true as warring powers devise self-pro-pelled projectiles, fearsome-looking multiple launchers, and take-off boosters for aircraft.

LEONARD ENGEL
ROCKET weapons, a genuine “secret development” of the present war, are playing an increasingly important rôle in military operations. Devices based on the rocket principle are in use to discharge projectiles, to trap and disable raiding aircraft, to increase the striking power of bombs, and to produce an extra take-off boost for planes carrying an overload of fuel or explosives.

PRECISION bombing by daylight, such as American Army flyers are doing with deadly effectiveness in Europe, is absolutely impossible for enemy airmen on at least nine days out of ten in several of the most vital defense areas of the United States. No bombsight can pierce the vast artificial fog which our Army’s new M-l smoke generator throws out as a screening blanket over military objectives.

JACOB EIERMAN
FLEW on the Japan raid, and it was the biggest show I’ve ever had a part in. I’d call it a thoroughly successful operation. I know that one bad break forced a change in the plan, and later led to the loss of our planes and a few of our men. But every plane went where it was supposed to go, found its targets, and planted its bombs right where they were supposed to fall.

THE recorder, which was popular in Shakespeare’s day, appears to be in vogue again. This simple musical instrument, resembling a flageolet, is now being manufactured in this country by William F. Koch at his plant in Haverhill, N. H. Made of South American cocobolo wood, of which Koch has a two-year supply, the instrument has a full chromatic scale with a range of a little over two octaves, and is made in soprano, alto, and tenor sizes. Unlike most other woodwinds, the recorder has no reed, its mouthpiece being provided with a “Apple” like that found on the ordinary whistle.

FOREMOST threat to the U.

With a surface speed of 17½ knots, which is as fast as many ocean liners, and a submerged speed of eight knots—at which tankers and cargo ships often cruise—the modern undersea raider is a very different proposition from that which prowled the oceans in the first World War.

GROUND walnut shells and resin, mixed with an acid catalyst and baked in bakers’ cookie ovens, are speeding the construction of warplanes. The “cookies” become drill jigs and forming dies capable of withstanding pressures of four tons. They have helped the Vega Aircraft Corporation save three months of tooling time in building warplanes at Burbank, Calif. M. Basolo, foreman of the Lockheed Aircraft Corporation wood shop, and Carl Hill, plastic expert, perfected the process.

POSTWAR commercial airports will be models of compactness, efficiency, and safety, according to Andrew J. Fairbanks, professor of aeronautical engineering at Rensselaer Polytechnic Institute, Troy, N. Y., whose conception of tomorrow’s airport is here illustrated. Long runways, expensive to build and maintain, will be obviated by catapults, circular take-offs, and flight-arresting gear, as well as by immobile “carriers” anchored in near-by rivers.

Snatching The Ingredients of Victory from air and water

ALBERT Q. MAISEL
AMMONIA has more than 2,000 peacetime industrial uses. In war, it is indispensable. A basic ingredient in the manufacture of explosives, it also hardens metal parts for planes, tanks, and guns; goes into nylon for parachutes and plastics for plane noses and turrets; freezes food for storage and shipment; makes fertilizers.

YOUR clothing, draperies, upholstery fabrics, and bed coverings can now be made fire-resistant and safe through the use of a new compound of ammonia— ammonium sulphamate—one of the latest developments of this important chemical. Treatment is as easy as washing clothes, and the fire-retardant solution can be made simply by dissolving ammonium sulphamate (not to be confused with the sulphate) in plain water at the rate of one pound in one gallon.

SHEARS as we know them probably date back to the sixteenth century or earlier, for they were apparently used by the Venetians. All shears fall into two classes: those whose blades are opened and closed by the pressure of one or more fingers and the thumb on the handle ends of the blades, and those which are closed by the hand, but opened by a coil spring between the blades or by spring action of the handle itself.

EUGENE MERKIN
To PREVENT a T-square from falling off the drawing board and to keep it aligned, the method shown above may be used. Cut a portion of clock spring to size, punch a hole in the center, and grind off rough edges. After shaping it as shown above, screw it to a piece of hardwood, which in turn is screwed to the blade of the T-square at such a distance that sufficient tension is obtained in the spring when the square is fitted to the BOARD.

A METAL ash tray can be prevented from sliding around on a polished surface or a glass-topped desk by drilling a small hole in the center of the tray and attaching an ordinary rubber suction cup.

HAROLD GRIMM
To LET a young child play with an electric train in safety, connect a door-bell button in series with the track and transformer. The train will run only while he holds down the button. Should it jump the track, a short circuit won’t cause trouble because he will release the button to put the train back.

Auger Bit Used in Drill Press
[no value]
[no value]
[no value]
E. C. HANLEY
TO MAKE an ordinary auger bit suitable for use in the drill press, cut off the square shank, then file off the thread of the spur. File the point to have three or four flat sides, similar to a pyramid. These flat sides form cutting edges that remove stock as they pierce the wood, whereas a coneshaped point is likely to cause the stock to split because it forces the fibers apart instead of cutting them.
